@ Vharlak: Like papill6n said, it requires Vurt's Groundcover files. For some reason, even though I only deleted Vurt's .esp's, I was getting texture problems around Fort Frostmoth:

But after reinstalling Vurt's meshes and textures, then reinstalling Taddeus' grass meshes fix, I actually found grass where it should be, or at least in Fort Frostmoth and Seyda Neen. I kind of assumed I can find it everywhere else, but I haven't actually tested this theory. Before I did these steps, there was nothing at all, and as you can see, the 'grass' at Fort Frostmoth looked more like something i'd rather not say. Now to deal with my Redesigned Vivec mod problem, missing elders and Better Heads. :facepalm:

@ Elaura: I hate to repeat it, but that happens to me all the time. lol

Yea, that is what my grass looks like exactly. Need to test these other files though to see what is up. Will edit this post with results.

I'm pretty sure not having the textures should not be affecting why the grass is only showing up in Fort Frostmoth though.

Now that i've tested it out a bit more, I notice there's a lot of grass missing around the Vivec area. I definitely see some, but there are many areas that are compeletely barren. I tried regenerating distant land with MGE and that's what the results were. So apparently something is still wrong somewhere.

Ok, it was user error. The grass shows up in the places I looked but I haven't checked Vivic.

Once I got the right package of textures and meshes everything worked great. I installed all of Vurts Meshes and textures and then the new NOM ones on top. Then I generated distant land with the 3 esps.
